This is from the Immigration and Foreigner Policy Headquarters of the Ministry of Justice.

We would like to inform you of caution as there has been a suspected case of voice phishing impersonating the Immigration and Immigration Policy Headquarters.

If personal information is requested by impersonating the Immigration and Immigration Office or the Immigration and Immigration Office (office) using an unconfirmed phone number (1533-6715, 1533-6725, or other similar numbers), voice phishing may be suspected and no harm will be done. We ask for your cooperation to avoid this.

* Please note that you will be asked to dial '0' and provide personal information to connect to the immigration office through the ARS (automated response system).
